To all whom it may conoem:

Be it known that I, Gnonon A. Msmsoma citizen of'the United States,residin at St. Paul, in the county of Ramsey and tate of Minnesota, haveinvented a new an Method of Dispensing Tooth- Paste, of which thefollowing is a specification.

My invention relates to means and ods for distributing or dispensing insmall portions tooth pastes and other similar substances; and the mainobject is to enable several persons to obtain, each of themindependently 'andseparately a. portion of such paste from a commonsource ina convenient and sanitary manner.

The invention is especially adapted for dispensing tooth paste in thetoilet room of hotels, depots and railway. cars.

' dispensing -modified. Fig. 6 is The invention involves .a methodconsisting in filling tooth paste into a tube of thin material, windingthe-tubeon a spool and then by an eas1ly operated. mechanism uncuttingit into the desired lengths or pieces, from which the operator thensqueezes the paste onto the tooth brush. The devices by which this maybe carried out may be of vafrom the structure and amodification thereofillustrated in the accompanying drawing, in whicb,- r 1 Figure 1 isaside view of my tooth aste device in a very serviceablef Fig. 2 is afront view of the device shown in Fi 1.

Referring to' the drawing by reference numerals, the frame ofv thedevice is composed of a cylindrical casing 1,having at its back lugs 2seeurable by screws 3 to any wall or other objectqwhile at the front ofthe casing is a' mechanism chamber 4, be secured by screws 5.120 thecasing-or made integral with the latter. Below said chamber 4 isarranged a receiving shelf 6, upon which the pieces Specification ofLetters Iatent- Application filed December 8, 1909. Serial No. 531,207.

One end of-the cylindrical casing is closed b a removable lid 8, which,as shown in Fig. 3, may extend also over the end of the chamber4, and,as shown in Fig. 2, 1t may even extend as a receiving shelf 6. .4

In tbecenter of the integral head of the casing is fixed one end of ashaft 9, whose other end is supported in a cavity 10. in the lid 8. Onsaid shaft/is revolubly mounted the spool 11, on which a tube 12 iswound after being made of very thin tin or other suitable material andled with a tooth paste. The outer end of the tube is passed through anaperture 1?:v in the casing and Patented Mar. 28, 1911. I

On said cam is pivoted a dog 24, which v by a spring 25 is heldengaged with a ratchet wheel 26 said ratchet wheel and a tube feedingwheel 27 are secured together and are revoluble on the shaft.

The feed wheel has a peripheric groove with roughened surface n asshown, so as to take sufiicient hold of the upper side of the paste suchhold the lower-side of the tube slides on cutting edge 29, with whichcoacts a cutter blade 30. (See also Fig. 7 Said blade is pivoted at 31to the end of the stud or frame tube, and to insure ose' free end formsa cam arm 22, and. when the lever is returned to 'normalopositi'on thecutter blade is raised by a spring arm 32 until it is above the tube 12and stops under a lug 33 on the arm 16.

34 may be applied to the ratchet wheel to guard against reverse turningof it.

In Fig. 4 is shown how a spring-pressed dog From the above descriptionit will be un-' dersto'od that in the operation of the device, the tubebeing filled with paste and put on the spool or reel 11 and in positionas explained, the lever 18 is simply swung forward to its limit, thiswill cause the cam 22 to swing the blade 30 downward and cut off thetube, and while the lever is returned to normal position the dog 24 actson the ratchet wheel, turning it and the feed wheel, so that the latterfeeds forward another three-fourths .of an inch or any otherredetermined length of the tube, which ength will be severed from thetube and drop upon the shelf 6 at the next forward operation of thelever, and so on each time paste .is

wanted. It will be observed that during the cutting operation of thetube, the dog 24 plays over the teeth of the ratchet wheel.

. tube.

In the modificationshown in Figs. 5 and 6, the. shaft is operated by ahand wheel instead of a hand lever, and the feed wheel 27* is fixed onthe shaft, and the frame arm or stud 16 is alittle different from 16 inFig. 3.-

On said shaftis also fixed a beveled ear 36, which turns another beveledgear 37 ed on a shaft 38, which is journaled in a frame arm 39- andcarries secured on its front end a.

two-blade cutter 40 (best shown in Fig. 6) either of which blades inpassing the cutting edge '29 of the fixed member 28 severe the 41 is asfirinfg-arm, or other dog, en'- gaging the teet o. the gear 36 toprevent reverse turning of the hand wheel and the feed wheel. In thismodification the length of the pieces cut from the tube may bepredetermined partly by the'diameter of the feed wheel and partly bydiameters of the beveled gears, the latter being in the present drawingillustrated as miter gears, but it is obvious that they represent-alsobevel gears of any variation of sizes, to indicate which I have termedthembeveled gears.

ItwiH' finally be understood that as the paste tube .is cut the jaws ofthe cutting device close the severed ends of the tube firmly during thecutting process, so that no paste is wasted, nor can germs or dirt ofany kind enter the tube or the paste, as thelatter is not exposed to theair before the operator squeezes it from the severed piece of tube forimmediate use upon the tooth brush.

Having thus described my invention, what I claim 1s: v

.The method of preparing receptacles filled with tooth paste consistingin preparing an elongated body of such paste covered with a thin film offlexible and ductile material and simultaneously severing transverselysuch .body into sections of desired length and A. M. CARLsEN,
